Here are a couple of pictures of my Prius right after I applied Paul's decals on the sides and back of the car. The tint on the windows (35% front, 50% everywhere else) was done a month ago. I haven't washed the car since I "waxed" the car three weeks ago with Zaino Brother's car polish; I have just been using a duster on a daily basis to keep it clean. The stuff goes on very easy and comes off pretty easy as well.
The black decals look great with the window tint. That really adds a lot to the white. I've done the grey on silver decals already, and am scheduled to tint this week.
